Aeolian geomorphology of the Namib Sand Sea

open access: yes, 2013
This review is concerned with the aeolian geomorphology of the Namib Sand Sea, part of the Namib Desert in Namibia, south-west Africa, concentrating in particular on studies made over the past 50 years.

Disturbance legacies in arid environments shape recovery of former agricultural land

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Increasingly, arid agricultural land is being permanently taken out of irrigated production due to more frequent drought, higher temperatures, and the overconsumption of groundwater, with important ramifications for ecological recovery.

Migration law of salt in compacted aeolian sandy soil

open access: yesYantu gongcheng xuebao, 2019
Aiming at the phenomenon of salinization diseases in the aeolian sand subgrade in desert areas, the change laws of water, heat and salt in compacted aeolian sand soils are investigated.

Soil inoculation enhances early‐phase reintroduction success in two rare plant species

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Reintroduction for conservation is an important measure to restore populations of vulnerable plant species. However, reintroduction success rates are relatively low. Inoculating reintroduced plants with facilitative microorganisms from native populations may enhance their performance.

Hydrologic effects of tidal wetland restoration in the subsided Sacramento‐San Joaquin Delta, California, United States

open access: yesRestoration Ecology, EarlyView.
Abstract Objective The Dutch Slough Tidal Restoration project in the Sacramento‐San Joaquin Delta involves flooding of delta lands; however, concerns have been raised that such flooding will increase the hydraulic pressures on subsided adjacent islands and threaten levee stability.

The Scale Characteristics and Formation Mechanism of Aeolian Sand Streamers Based on Large Eddy Simulation

open access: yesJournal of Geophysical Research - Atmospheres, 2019
Aeolian sand transport near the surface in the field often occurs in the form of sand streamers, which is very important to understand in‐depth the physics of aeolian transport and accurately predict the sand transport rate. In this paper, sand streamers

Quantification of dryland depositional environments across contrasting fluvio‐aeolian and fluvio‐lacustrine transects: An integrated subsurface and outcrop analogue study of the Organ Rock Formation, Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT The standard subdivision of a distributive fluvial system (DFS) into proximal, medial and distal zones is typically based on the proportion of channel bodies and/or the degree of channel amalgamation, reflecting a downstream fining trend towards a mud‐prone terminal pinch‐out.

Time-Varying Compressive Strength Model of Aeolian Sand Concrete considering the Harmful Pore Ratio Variation and Heterogeneous Nucleation Effect

open access: yesAdvance in Civil Engineering, 2019
The aim of this study was to analyze the influence mechanism of aeolian sand on the mechanical property of concrete and establish the time-varying compressive strength model. Test studies on the development of concrete’s compressive strength with aeolian

Perennially ice‐covered lake facies as proxies for ice cover properties and climate: Insights from Lake Joyce, Antarctica

open access: yesSedimentology, EarlyView.
ABSTRACT Process‐based depositional models for perennially ice‐covered lakes (PICLs) are important for interpreting palaeolake deposits and their connection to past climate. PICLs are only stable under specific climate states, and unlike other ice‐free or seasonally ice‐covered lakes, PICL deposits generally have bimodal grain sizes: mud introduced by ...

Control Effects of Five Common Solid Waste Backfilling Materials on In Situ Strata of Gob

open access: yesEnergies, 2019
Solid backfill mining as a green mining method has already been successfully applied in many mine sites. Higher requirements for the backfilling materials have been put forward in special regions, such as shallow coal seams, ecologically susceptible ...
